Sometime in the last 50-100 years, "art" became something to be "understood" by exclusive, pretentious, in-the-know types who pretend to admire ugliness because they understand it, or something.
Before that, it was pretty much universally accepted that visual art was for looking at, and therefore if it is ugly, you are basically being rude to the onlooker, regardless of the "message" behind it.
These days, a certain minority feel superior when others say "I don't like that, it's ugly", they can respond "Aha, you are ignorant, it is meaningful, I am cleverer than you because I claim to like what is ugly". But really they are actually seeing less, not more.
So I don't subscribe to that exclusivist view of art. I think that art can be both meaningful and beautiful, and that when it is beautiful, more people can access its meaning. And this doesn't make me ignorant, any more than the boy pointing out the emperor is naked.
